Pruning walnut tree buds to master the period and characteristics, not only to grasp the pruning period, but also according to the walnut tree branches and buds characteristic pruning walnut trees in order to prevent the occurrence of bleeding, and can achieve enhanced growth potential extension of branches update results branches extend Zhizu result, the results of years, to improve the crown bore the light, so that the tree growing strong prosperous, to achieve yield goals. After the leaf spring, after the autumn harvest walnuts, walnut tree before pruning deciduous tree is a good time to avoid injury streams. Walnut tree branches grow strong apical dominance, shoot to the top easy to grow prosperous branches; branches branching angle, horizontal branches mostly adult tree growth; behind buds on the branches, the growth and development to enrich its force and give birth to sprout shoots growth potential, both sides are better than buds and shoots back; water absorption speed behind the buds on the branches, shoots faster than the back. Walnut branch shall grow, often behind the branch and other branches competitive growth of the phenomenon, resulting from the structure of the main body of an unknown tree, causing the canopy to get bad light. After the formation of the results of branch behind branch results, easy to drooping branches, growing weaker. Branches, the lower buds, dry yourself off more easily formed bare belt. Long dormant buds life branches at the base, the case can stimulate germination, taking long sticks. In the shoot growth of dormancy, such as causing a wound to the shoots, bleeding occurs. According to the growth habit of the walnut tree branches and buds, after the walnut harvest, before the tree leaves, pruning should be carried out as follows: Trim back branches, back under the branches. When the branch back as the main branch extended head, to make the main collateral branches above, the main branch growing stronger than the collateral. Usually should be back next branch Thinning. Increase the amount of branches, culture results Zhizu. By increasing the amount of branch stub method. With slow release method, on both sides of the main branch, collateral, cultivate robust large, medium-sized fruit branch groups. When cutting back branches branches to stay shorter, to prevent the branches bare. Results for the old branch to timely retraction. By the use of dormant buds sprouted branches update crown. Improve canopy lighting. For the growth of dense crown bore branches, overlapping branches, growing competition crown peripheral branches, crossing branches, sparsely between appropriate or retract. The results prompted the formation of branches. Erect flourishing branches, were leveled down slow release, easing growing branches, formed to promote the results of branches. Behind the control sticks and drooping branches growing, walnut branches opening angle, behind the drooping branches and branch growth and back sides of sticks and branches grow, competition for nutrients. It is to be controlled behind the drooping branches and branches growing to avoid the phenomenon of the relocation site results.
